    Can this be straightened? If so, how?

    Also, are the two rating nuts:
    1. Used to lock the nuts in place
    2. The lower nut is used as a fine regulation
    3. Just an extra one someone added
    Thanks,
    Tom

    I think the two nuts are used to lock the adjustment.

    I have seen several instances of a single nut that creeps downward over time and some companies took extra measures with different devices to keep this from happening.

    So, slightly jamming two nuts together is a simple way to solve an annoying problem.

    Clocks seem to work just fine with a warped stick. Replaceing it is the only cure AFAIK.

    There is a way, but it's not worth the trouble. What Willie said.

    Is this out of a Long Case?

    The only way I know of to remove warps and dents in unfinished wood (without cutting, planing or otherwise mechanically re-shaping it) is to expose it to water/moisture and then apply corrective force until the wood dries. If the wood is finished so that moisture can't enter easily, I don't think it can be attempted without stripping the finish.

    Of course you could always replace it and reuse the hardware as Willie has already suggested

    I tend to agree with the advice of Willie and bangster... unless it really bugs you, leave it as is.

    you could clamp it straight between two 36" levels (for example) and leave it in the bathroom where you shower for a week or so and see if that helps... but it's not that bad.

    otoh, i have found those second regulating nuts to be nothing but a PITA... lose it, use one.

    Thanks for the recommendations guys. I plan to leave it because it is original and otherwise in fine condition. But my OCD cringes a little when the tick and tock are not centered even though it is in beat. o_O

    You could make one easy enough. Your local lumber supply will have trim pieces that are just about the right size and shape.

    To straighten warped wood it has to be wet and then bent slightly beyond the straight (to allow for the natural spring in the wood) and then held in that position and allowed to dry. I have successfully straigntened the butt on a Martini-Henry using damp cloths and a vise. Took a few days but it was successful!

    Thanks for the additional suggestions. It's nice to hear multiple ideas.

    To expand on previous remedies:
    Put it under stress (somehow) so the bow is corrected.
    Put a damp cloth on it.
    Go over the cloth with a clothes iron (steam or otherwise) to provide heat and moisture.
    Allow to cool
    If it still needs more straightening, do it again.
    Wash, rinse, repeat.

    Bangster's method can also be used to raise dents in wood (as long as the fibres aren't broken). I have raised dents in gun stocks that way and it works well.

    If the steam will penetrate the paint, that will work.

    This is one of those good tips that you forget about when you need it because you don't use it frequently enough. I need more RAM and better search tools. ;)
